The Wall Street Journal published an op-ed by Phil Gramm and Mike Solon pushing "pro-growth tax reform" and criticizing "regulatory burden" and "antibusiness bias." The Journal did not disclose that the authors are partners of an anti-regulation lobbying firm, and that Solon is frequent business lobbyist.

Gramm is a former Republican Senator, and Solon worked as a Gramm Senate staffer for over a decade. They run Gramm Partners, a D.C. lobbying firm. The firm's website states that it works "on the issues that matter most to financial companies" and has "a track record of delivering major accomplishments -- and stopping bad deals in their tracks." The two also run US Policy Metrics, "an economic and public policy research firm serving asset managers, hedge funds and the investor community."

The Journal's identification of Gramm and Solon simply states: "Mr. Gramm, a former chairman of the Senate Banking Committee, is senior partner of US Policy Metrics and a visiting scholar at the American Enterprise Institute. Mr. Solon was a policy adviser to Senate Republican Leader Mitch McConnell and is a partner at US Policy Metrics."

Gramm and Solon's op-ed complains that Democrats won't lower tax rates and have a "misplaced perception of the importance of the inequality debate." They added: "A pro-growth tax reform will not undo this administration's doubling of the federal debt held by the public, its tax increases, increased regulatory burden or antibusiness bias. But it would be a major movement in the right direction."

Media Matters has documented how the Journal has repeatedly failed to disclose relevant ties about writers in its editorial page.

The New York Times was forced to issue two corrections after relying on Capitol Hill anonymous sourcing for its flawed report on emails from former Secretary of State and Democratic presidential candidate Hillary Clinton. The Clinton debacle is the latest example of why the media should be careful when relying on leaks from partisan congressional sources -- this is far from the first time journalists who did have been burned.

Several Fox News figures are attempting to shift partial blame onto Samuel DuBose for his own death at the hands of a Cincinnati police officer during a traffic stop, arguing DuBose should have cooperated with the officer's instructions if he wanted to avoid "danger."

Iowa radio host Steve Deace is frequently interviewed as a political analyst by mainstream media outlets like NPR, MSNBC, and The Hill when they need an insider's perspective on the GOP primary and Iowa political landscape. However, these outlets may not all be aware that Deace gained his insider status in conservative circles by broadcasting full-throated endorsements of extreme right-wing positions on his radio show and writing online columns filled with intolerant views that he never reveals during main stream media appearances.
